Question 1 of 5
The resting potential indicates that the inside of the neuron is ________ compared to the outside.
Correct Answer: C
Rationale: The resting potential of a neuron, typically around -65mV, indicates that the inside of the neuron is negatively charged compared to the outside. This charge difference is maintained by the sodium-potassium pump and the selective permeability of the cell membrane to ions. The resting potential is essential for the neuron's ability to generate and transmit nerve impulses, as it provides the electrical gradient necessary for action potentials.
Question 2 of 5
The brain and spinal cord are the organs of the ________ .
Correct Answer: A
Rationale: The brain and spinal cord are the primary organs of the central nervous system (CNS). The CNS is responsible for processing and integrating information received from the peripheral nervous system (PNS). The autonomic nervous system (ANS) is a division of the PNS, and cerebrospinal fluid (CSF) is a protective fluid surrounding the CNS. Therefore, CNS is the correct answer as it directly refers to the brain and spinal cord.
